Answer:

Step-by-step explanation:

We know that for a square of side length s, the perimeter is given by:

P(s) = 4*s

a) If initially we have s = 1cm, then the initial perimeter is:

P(1cm) = 4*1cm = 4cm

if now s changes to 1.5cm, the new perimeter will be:

p(1.5cm) = 4*1.5cm = 6cm

So the side length increased 0.5cm, and the perimeter increased 4 times that, 2cm.

b) We can define the change in side length as Δs, then if the initial side length is s, the new side length will be written as:

s + Δs

using this in the perimeter equation we get:

P(s + Δs) = 4*(s + Δs) = 4*s + 4*Δs = P(s) + ΔP

We can see that ΔP = 4*Δs

c) We already know the formula, it is P(s) = 4*s, the graph can be seen below.

d) We need to solve 8 = 4*s

To get this, we need to isolate s.

s = 8/4 = 2

s = 2

This means that if the perimeter is 8cm, then the side length must be 2cm

e) P = 4*s

is the perimeter in terms of the side length, we want to get the side length in terms of the perimeter, we just need to divide both sides by 4:

s = P/4

f) The formula we got in (e) is the formula P = 4*s divided on both sides by 4.

That is the relation between the two formulas.

If Mike payed $20 every two hours, then the unit rate would be $10 per hour.

El tamaño del paso se puede determinar mediante progresión aritmética.

Para determinar el tamaño del paso, usamos lógica aritmética de prorrateo.

Del formulario de progresión aritmética, donde:

[tex] a_{n} \: = a \: + \: (n - 1)d[/tex]

n = número de términos (número de pasos) = 9

d = diferencia común (tamaño de los pasos)

[tex] a_{n}[/tex]

Valor del enésimo término = 2

a = primer término = 1

Usando los parámetros, podemos obtener el valor de d que es el tamaño de cada paso.

Ingresando los valores en la fórmula:

2 = 1 + (9 - 1) d

2 = 1 + 8d

2 - 1 = 8d

1 = 8d

d = 1/8

d = 0,125

Por tanto, el tamaño del paso es de 0,125 metros.

Answer: 28,000-2,000x= y

Step-by-step explanation: 28,000 is the starting cost. You would have to then multiply 2,000 by the amount of years it depreciates you find the total amount of value lost during the depreciation period. Once the total depreciation is determined you would subtract the starting cost from the depreciation amount. Determining Y, the value of the car after a certain amount of years.

Given that a new car worth $28,000 is depreciating in value by $2000 per year. The linear equation that models the car's value, y, in dollars, after x years : y = 28000 - 2000x.

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.

Present car's value = y dollars

Number of years passed = x years

Linear equation that models the car's value =

y = 28000 - 2000x

($2000 depreciates every year. So the current value of the car is original price minus the $2000 subtracted every year i.e., x times $2000)

Step-by-step explanation:

4000 Watts means that if you run the machine for one hour, you are using 4000 watt-hours or more commonly used 4 kWh (kilo means 1000).

for 14 cents per kWh we have then

14 × 4 = 56 cents per day

now, if the other model uses only 2000 Watts and still only needs 1 hour for the same job (which is in reality NOT a given, very often such a machine means that it will have to run close to 2 hours) it would cost

14 × 2 = 28 cents per day, saving 28 cents per day.

for a year running the dryer daily

we would save

28 × 365 = 10220 cents = $102.20 savings per year
